I have an HP h8-1050 running the legacy BIOS (specs here at the HP site: HP Pavilion HPE h8-1050 Desktop PC Product Specifications | HP® Customer Support ) that came with an AMD Radeon HD 6850. I'm trying to get my PC running the new PlayerUnknown's Battlegrounds but the minimum system requirements call for an AMD Radeon HD 7850. Where can I go to find a list of AMD graphics cards that are compatible with my system so I make sure I buy the right one? Thanks in advance.

I do have both the available slot and have recently upgraded the power supply. I'm looking for guidance on a graphics card that is compatible with my exact model referenced above. I've read that it is difficult to upgrade my model and I've already tried a GeForce GTX 670 with no success. Any ideas?

In addition to looking for a new graphics card for the model referenced above, I'm now having problems with my current graphics card also referenced above. When the GTX 670 didn't work, I reinstalled the factory AMD Radeon HD 6850 and now get 6 beeps at startup and no display. Any ideas on what happened to the factory graphics card?
